The Florida medical malpractice Complaint filed on September 17, 2026 states, in part:

Plaintiffs Natalie Strong and Joshua Strong, by and through undersigned counsel, sue Defendants Brown Fertility Associates, P.A.; Samuel E. Brown, M.D.; and John Doe Defendants 1 through 10, and in support state as follows:

  1. Joshua and Natalie Strong came to Brown Fertility with the dream of having biological children of their own. They trusted Brown Fertility, as well as its founder and owner, Samuel E. Brown, M.D., with the family they hoped to build.
  2. That trust was betrayed.
  3. Brown Fertility used another man’s sperm to create the Strongs’ embryos. Brown Fertility transferred those embryos into Natalie’s body. The Strongs are now raising a daughter whose paternity test confirms that another man, not Joshua, fathered her.
  4. Joshua’s cryopreserved sperm is gone. Brown Fertility cannot, or will not, say where it is, whether it remains in storage, whether Brown Fertility discarded it, or whether Brown Fertility used it to impregnate another patient. The Strongs do not know whether Joshua has biological children, fathered without his knowledge, being raised today by other Brown Fertility patients who have no idea.
  5. Brown Fertility’s failure was not an isolated incident. Brown Fertility almost certainly used the same unknown sperm to create the embryo Natalie miscarried, and to create the three embryos that remain in Brown Fertility’s cryostorage.
  6. Despite irrefutable DNA evidence, Brown Fertility and Dr. Brown have refused to admit what they did, refused to account for Joshua’s missing sperm, and refused to take responsibility. Brown Fertility and Dr. Brown have left the Strongs no alternative but to bring this lawsuit.
  7. This action seeks redress for what Brown Fertility took from the Strongs: the integrity of Natalie’s body, Joshua’s irreplaceable genetic material, and the biological family the Strongs paid Brown Fertility to help them build.
  1. The Strongs chose Brown Fertility, a fertility practice that publicly advertises itself as “a nationally recognized fertility center personally invested in your success,” is named by Newsweek among “America’s Best Fertility Clinics” in 2025, and brands its work “Conceiving Miracles.” The Strongs paid Brown Fertility tens of thousands of dollars for its services. Brown Fertility represented to the Strongs that the embryos Brown Fertility would
    create, store, and transfer would be the joint genetic product of Natalie’s eggs and Joshua’s sperm.
  2. On February 19, 2024, Joshua underwent surgical sperm retrieval. The procedure was a percutaneous epididymal sperm aspiration, or “PESA”, a scrotal procedure performed under intravenous sedation in which a needle is inserted through the skin of the scrotum into the epididymis to aspirate sperm. Joshua’s retrieved sperm was then entrusted to Brown Fertility for cryopreservation and storage.
  3. Joshua submitted to that surgery for one purpose: so that his retrieved sperm could be used to fertilize his wife’s eggs and create biological children of their union.
  1. Within the first day of life, routine newborn blood typing produced a result that did not fit. The Strongs’ daughter typed Blood Type B Positive. That result is biologically impossible given Natalie’s blood type, O Negative, and Joshua’s blood type, A Negative.
  2. The Strongs arranged for certified DNA testing through DNA Diagnostics Center, a nationally accredited testing laboratory. On June 13, 2025, DDC issued its certified report. The report confirmed that Natalie is the biological mother of the daughter she carried and delivered, conceived from the embryo Brown Fertility transferred into her body, and that Joshua is not the biological father. There is only one possible conclusion: Brown Fertility used the wrong sperm.
  1. Brown Fertility has refused to identify what became of Joshua’s cryopreserved sperm. Brown Fertility has not, to date, told the Strongs whether Joshua’s sperm is in its freezers, in a biohazard bag, or in the womb of another woman.
  2. What happened to the Strongs did not occur because IVF is unreliable. It occurred because Brown Fertility’s specimen identification, labeling, witnessing, and chain of custody controls failed in elementary ways, the very failures that the most basic IVF quality assurance protocols are designed to prevent.
  1. To this day, Brown Fertility has refused to identify what became of Joshua’s cryopreserved sperm. Brown Fertility has not offered the Strongs an explanation or an apology, and has refused to take responsibility.
  2. Faced with irrefutable evidence of catastrophic negligence in its own laboratory, Brown Fertility has chosen silence. The Strongs have no path to answers other than this lawsuit.
